Default How can I tell if my USB drive is bad?

Hello,

Like the title asks. I have an old SanDisk Cruzer - 128MB. I plugged it into my new laptop and nothing - it was recognized, but didn't configure it to be mounted. That is, I got the umass0 and scsibus0, but no mention of the sd0 in the messages when I plugged it in.

I thought maybe there was something wrong with the USB port or kernel until I thought to try another USB drive - a newer 2GB Cruzer. And to my relief it was recognized, configured and I was able to mount it. But that raises the question of whether the 128MB drive is then bad. It is able to be mounted on my other computers running Slackware and Windows and on the Windows machines at the University. But, this drive is no spring chicken - and I have corrupted the data on it more than once. Is there a way for me to definitively test this thing?
